INSTALLATION PROCEDURE
The Model H1107.8 Water Cooler assembly requires installation of the mounting frame as
described in Steps 1 - 2, then mounting the fountain bowl assembly as described in Steps 3 - 6,
and finally completing chiller water and electrical connections and starting chiller per Steps 7 -
11. First check that all required parts are received.
Grounding may cause electrical feedback into the electric drinking fountain causing an
electrolysis, which creates a metallic taste or an increase in the metal content of the
water. This condition can be avoided by using dielectric couplings in the assembly. The
waste line, which is supplied by the installer, should also have a dielectric (plastic)
coupling to completely isolate the assembly from the building plumbing system.
